TIRE-FILLING CQMGSITXQN.

Application .filed March l:y

To all whom 'it may concern Be it known that l', ,Enmnn Onfvnn, a citizen of the United States, residing at Daytona, in the county of Volusie anni citate of `Florida, have invented certain new und useful improvements in Tire-Filling Cour positions, of which the following is n sprcii cation.

'lhis invention relates to tion et' metter for use as a tires.

One object of the invention is to provide a. filler which will ndhere firmly to the inner will of the tire, which will stand all heat conditions to which the tire is suhg'ected, and which will not melt, harden or eolien to an objectionable degree, crumble or otherwise deteriorate with nge or lese its elasticity.

A further object of the invention is to provide a normally solid filler possessing the defined charaetericties and which may be rendered plastic und simultaneously forced into any ordinary type of tire, thus obvieting the necessity of injecting the iller in a liquid starte and using solvents, gases or other agents liable to cause injury to the tire, or olf requiring tires of special. type or construction A still further object of the invention is to provide a composition of mutter hy means of which single or double tube tires may be easily and expeditiously illed, and a strong, durable, puncture-proof and highly resilient tire produced.

In carrying my invention into practice l provide u filler which is normally solid and, resilient and. capable of resisting heat he youd any temperature to which the tire is subjected, say up to ,180? F., hut which is capable of being rendered plastic under a predetermined degree of pressure and frictionnl heat, so that hy the use of suitable mechanical means for producing mechanical rassure and heet it may be rendered plastic and forced into the tire. To this end. the iller is formed of e composition of blown cotton seed oil (corn or other vegetable oil?, gilsonite, flowers of sulfur, copper oxid, zinc oxil and Whiting. The proportions in which these ingredients are combined depende upon the size oi the tire and the load weight to he carried thereby, und hence the roportions muy he yuried,"hut the follow mg combination has been found generally satisactory: cottonlseed or equivalent regea novel eolnposi filler :lor resilient.

A large proportion of this sulfur is driven oli during the preliminary heating of theA oil und gilsonite., hut a proportion remains.y reducing the amount of lowere of sulfur required for vulcunizing action. AS. honorer, the ernennt el euli'ur containeiifin the g' inte varies, and as it important to pre. .it the retention of :in excess amount in the mixture, or of any free Sulfur in the coinliiletcd product, l'. employ the con per und zinc oxide both as'illers and Sulfur reducing agents. 1l'hese oxiris in some ninnner, as pruetical experience showsSI reduce or render innocuous any excess of Sulfur., and promote amalgamation and vulcanizetion of the mixture, so 'that a perxnmiently elastic product nill he formen which will not harden or hcconie'hrittle under atmen plierie inluenees. ln this respect the prod uct differs from any other like product with `which I mn familier. For the purpose' of introducing this composition, lf force the sante into the tire under pressure ficient heet to render it plastic for introduitu tion by suitable mechanical means, such as u lilling machine of the type shown in the accompanying drawings. in Jvhic'n:-- f

Figure l is a view illustrating the 2115.- ehine in eide ein: ion anni ,also Showing the arrangement of the machine relative 'to e tire to he filled. FigV i3 is e view, partly in vertical section and remy .in elewtioni detached from the machine. It will, of conrse, be understood that the machine may be heated to supplement the frictional heat for the urpose of increasing the plasticity of the trilling substance when required or desired.

It will be observed that by the eomposition described a filling possessing desirable qualities is not only provided, but that the use of gases, chemicals and solvents liable to injure the tire is also avoided, and these and other objections incident to employing a primarily liquid iller obviated,

Having thus described the invention, what I claim as new is The herein-described tire filler, compris ing a solid resilient composition of cotton seed oil, 7? lbs., gilsonite, 11 lbs., owers of sulfur, 14% lbs., copper oxid, l lbs., zinc oxid. 3 lbs., and Whiting, 3?; lbs

In testimony whereof I affix my signature in presence of two witnesses.
